Subject: build error at mm_unstable shmem.c: undefined reference to `vma_thp_gfp_mask')
Date: Wed, 28 Aug 2024 10:48:01 -0700	[thread overview]
Message-ID: <CABi2SkWmHaMbsJ7EXge7b4j_XpLCjWQfO6D2v0vY-PAoj5ePaA@mail.gmail.com> (raw)

Hi,

When I enlist to mm_unstable branch, there is a build error:

ld: vmlinux.o: in function `shmem_swapin_folio':
shmem.c:(.text+0x21b5d5): undefined reference to `vma_thp_gfp_mask'
make[2]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1
make[1]: *** [/usr/local/google/home/jeffxu/mm/Makefile:1156: vmlinux] Error 2
make: *** [Makefile:224: __sub-make] Error 2

And it is fixed by adding CONFIG_TRANSPARENT_HUGEPAGE to .config

Is there a recent change in shmem.c and adding this dependency ?
Maybe updating Kconfig or adding an ifdef ?

Thanks
Best Regards
-Jeff
